EDWARD M. MARSHALL PAIENTEDJms m2 SHEET 3 0F 3 h QE INVENTOR. EDWARD M. MARSHALL FOOD COOKING GRILL This invention relates in general to cooking devices and more particularly to a portable electric cooking grill for rapidly and uniformly cooking food thereon under the weight of a skillet plate, which device includes a slot for manually receiving the skillet plate in a choice of angular positions for food removal and temperature maintenance and also for upright positioning in an idle position.

Reference is had to applicants pending application, Ser. No. 77,548, filed Oct. 2, 1970 now US. Pat. No. 3,623,422.

A principal object of the invention is the provision of an improved portable grill incorporating several features not included in the aforesaid pending application, such as the use of a single casing member formed to properly receive and position the grill plate, and one or two skillet plates including means within a rear slot along the grill plates for holding each skillet plate at each of two selected predetermined angles with respect to the grill plate for the removal of food thereunder and maintaining a predetermined temperature in each plate from the heated upward draft from the casing, including the manual raising of the plates for descent to idle position in the slot.

A further object of the invention is the provision of a detachable serpentine shaped heating element assembly under said grill plate and supported by marginal ledges in opposite ends of the casing with the electric terminals thereof positioned in a tubular entry in one side of said casing for connection to a source of electric power.

Another object of the invention includes the provision of a frontal elongated opening in the casing for receiving a slidable drip pan supported on opposite edges on the inner sides thereof for positioning the pan directly under the grill plate a predetermined vertical distance from the heating element assembly.

A further object ofthe invention provides for the removal of the heating element assembly and the use of briquettes or other fuel positioned in the drip pan or similar receptacle for heating the grill and skillet plates.

These and other objects and advantages in one embodiment of the invention, are described and shown in the following specification and drawings, in which:

FIG. 1 is a top plan view of the cooking grill with portions thereof broken away.

FIG. 2 is a front elevation of the grill shown in FIG. 1.

FIG, 3 is a left side elevation of the grill shown in FIG. 2.

FIG. 4 is a cross sectional view taken through section line 4-4, FIG. 1.

FIG. 5 is a cross sectional end elevation taken through section line 55, FIG. 1.

FIG. 6 is a cross sectional end elevation taken through section line 66, FIG. 1.

FIG. 7 is a left hand end view with a portion broken away and an illustration of partial operation.

FIG. 8 is a perspective view of the grill shown in FIG. 1 in idle position.

FIG. 9 is an alternate fragmentary cross sectional view showing a modified grill and skillet plate.

Referring to FIGS. 1, 2, and 3, a generally rectangular hollow metal casing l is provided with a gravity positioned frame 2 resting on the upper edge thereof having a planar upper surface. An integral tubular electric socket entry 3 extends from one end of the casing.

A foraminated grill plate 4 is adapted to be retained by gravity in a recess in the upper portion of the frame 2, as shown. A single or double rectangular flat skillet plate 5 is loosely retained in the aforesaid recess above the grill plate and provided with a central integral bridge shaped extension 6 formed over the frame 2 and terminating in a handle 7 for manipulating the plate 5 for weighting food upon the grill and cooking food resting on the grill or on the upper side thereof. The handle is also used for tilting the plate to a stand-by or idle position, to be hereinafter described.

A removable armored electric heating element 8 is positioned under the grill 4 and terminates in a pair of electric terminals 99 within the entry 3 retained in a heat resistant insulation means 9a. The electric element is supported by a pair of edgewise crossed vertical interlocked strips 10 which are retained by integral brackets 11 at opposite ends thereof which bear upon a ledge 12 at opposite ends of the casing 1.

Referring to FIG. 2, an elongated opening in the front lower portion of the casing permits a tray or pan 13 having a flange l4 projecting around the edge to be supported by a pair of projecting members l5-l5 extending from opposite inner ends of the casing l which include at the rear end of each a stop 16 for positioning the pan 13 directly under the grill 4,

Referring to FIG. 4, the skillet or plate 5 normally rests on the grill 4 when in use and is coated with a non-stick plastic, such as Teflon 17, on the entire upper side thereof to prevent food cooked thereon from sticking.

Referring to FIGS. 4, 5, and 6, four stop projections 18 extending downward from the underside of frame 2, as shown, precisely register the frame 2 and the grill plate within the top ofthe casing 1.

Referring to FIGS. 1, 5, and 6, it is to be noted that slot 19 is provided between the rear edge of the grill and the adjacent inner side of the frame 2, which provides for receiving and passing the cooking skillet or plate 5.

Referring to FIG. 7, when the plate 5 has served its purpose, it may be moved by handle 7 into idle position by raising approximately ninety degrees and permitting the plate to descend by gravity through slot 19 and descend to stop against projecting ledge members 15 on each side of the body and come to rest leaning rearward with the lower edge of the plate against the stop 20 at each side of the body, as shown.

It has been found in certain cases that it is advantageous to maintain a higher than room temperature in the plate 5 while the heater is energized by permitting the plate to rest against the lower inner corner of the frame 2 and the upper outer corner of the grill, as shown. This position will maintain a predetermined holding temperature in the plate for subsequent use. A lower temperature may be maintained in the plate by permitting the plate to rest on the shoulder 12 of the casing and the outer upper lateral corner of the grill, as shown.

The perspective view of FIG. 8 represents the grill at rest with the pressure plate or skillet in idle or rest position and the drip pan partially withdrawn.

In operation and under the assumption that an energized electric power cord terminating in a connected plug, which may include an adjustable thermostat, is inserted in the entry 3 connecting terminals 9 to energize the heater assembly 8, the direct radiation therefrom will heat the grill plate 4 rapidly, which heating is accelerated by the up-draft caused by the enclosure of the casing I. It is obvious that one or two skillet plates 5 will receive maximum heat when resting by gravity upon the grill plate. When the temperature of the grill plate has reached a predetermined maximum, then either or both of the skillet plates is raised to a selected angular position by the handle 7 and the food, such as hamburger, steak, or the like, is placed directly on the heated grill plate and the skillet plate lowered into gravity contact with the food. Thus, the exposure of the food to heat from both bottom and top completes the cooking cycle in a relatively short period of time. The skillet plate is then raised to a predetermined angular position and the food removed in the usual manner. If re-use of the device is desired, the skillet plate is left in the angular position to maintain a reasonable temperature therein.

FIG. 9 shows an alternate construction wherein the frame 2a is retained by four pins 18a in the same manner as previously used in the inside corners of the frame 1. However, the top surface of the grill plate 4 is now coplanar with the top surface of the frame 2a.

FIG. 9 also shows a non-stick coating, such as Teflon 17, on the upper sides of the frame and grill plate, as well as on both sides of the skillet plate for obvious cleaning purposes.

In the event that the cooking of other foods, such as pancakes, eggs, etc., is desired they may be cooked on the top surface of the cooking plate when it is lowered over the grill plate, as shown in FIGS. 1-3, and handled in well known manner. When a cooking cycle is completed, the heating element may be deenergized and each or both of the skillet plates may be placed in idle position by raising handle 7 to a substantially upright position with the rear end thereof in the slot 19 adjacent the grill plate and permitted to descend by gravity to come to rest on the projecting ledge members 15, leaning rearward with the lower edge of each plate forward against the stop 20 at each side ofthe body.

It is apparent that any fat or grease drippings from the cooking will descend from the grill plate and fall into the drip pain when properly positioned.

A well known adjustable thermostat may be included in the power cord plug for insertion in entry 3 for automatically controlling the temperature of the cooking grill plate via heat conduction through the casing into the entry tube 3.

It is also apparent that the grill plate may be readily heated by detaching. the heating element and burning well known briquettes or other solid fuel in the drip pan or a similar receptacle when the receptacle is positioned under the grill plate.

Certain modifications in construction are intended to come within the scope and teachings of the above specification.
